Description
- The invention relates to eyeglasses, particularly to a turning mechanism of brackets and temple arms without requiring the use of joints.
- In conventional eyeglasses, brackets integrated with a front frame and temple arms are collapsibly connected to each other by joints serving as a turning mechanism.
- However, the eyeglasses of this type have such drawbacks that the temple arms generate a play because screws and bolts serving as the shafts of joints loose when the temple arms are repeatedly collapsed.
- Accordingly, the screws must be re-screwed periodically by an exclusive driver, etc., which has been very troublesome.
- Under the circumstances, there have been developed many turning mechanisms having a simple structure with no use of screws, bolts, etc., which are different from the turning mechanism using joints.
- Among them, there are some turning mechanisms capable of very simply attaching the brackets and temple arms to each other.
- For example, a turning mechanism shown in JP-A 9-325303 is adapted so that spring pins are fixed to temple arms by brazing, and rings are fixed to brackets so that the spring pins are mounted on the rings, leading to the swinging movement of the temple arms. That is, the turning mechanism includes shafts or spring pins which pressed into the shaft supports or rings to give friction force thereto.
- In this case, since the spring pins are rotatably pressed and held by the rings, they can give resisting force to the swinging movement of the temple arms.
- Further, this turning mechanism has an effect that the temple arms can be attached to the brackets in a snap.
- However, in this turning mechanism, brazing is performed to attach steel spring pins to the steel temple arms.
- Since the spring pins are different from the temple arm bodies in function, it is necessary to manufacture them by different materials. However, the materials are limited to the range of type because they are brazed.
- For example, it is preferable that the steel spring pins are changed to an elastic material such as plastics having the same elasticity of the temple arm bodies in order to render the eyeglasses light in weight. In such a case, it is practically difficult to fix the spring pins to the temple arm bodies by brazing.
- Still further, recent eyeglasses employ very small steel wires as the material of the temple arms in view of light weight thereof, which causes a problem that a jointing portion between the spring pins and the temple arm bodies is inferior in strength because of a small jointing area.
- The invention has been made to solve the aforementioned problem.

- A second aspect of the invention resides in the turning mechanism of the first aspect of the invention wherein the temple rod is mounted on the shaft by engaging a bent tip end of the temple rod which passed through the shaft in a recess provided at the outer periphery of the shaft.
- A third aspect of the invention resides in the turning mechanism of the second aspect of the invention wherein the tip end of the temple rod extends upward and downward.
- A fourth aspect of the invention resides in the turning mechanism of the first aspect of the invention wherein the temple rod is mounted on the shaft by engaging a sectorial tip end of the temple rod which is enlarged at both sides in an expanded space formed in a through hole of the shaft.
- A fifth aspect of the invention resides in the turning mechanism of the first aspect of the invention wherein the guide groove has a recess in which the temple arm is engaged to prevent the temple arm from being collapsed.
- A sixth aspect of the invention resides in the turning mechanism of the first aspect of the invention wherein the shaft of the temple arm has a flexible material serving as a cushion between a part of the temple arm and the bracket when temple arms are erected.
- A seventh aspect of the invention resides in the turning mechanism of the second aspect of the invention wherein the shaft support hole of the bracket has a longitudinal groove whereby the temple arm is temporarily fixed at a certain angle when the tip end of the temple rod is engaged in the vertical groove.
- An eighth aspect of the invention resides in the turning mechanism of the first aspect of the invention wherein the notched portion is provided within an angle formed by the temple arm when swung.

temple rod 11 constituting thetemple arm 1 and Figs. 3(A) to 3(C) show theshaft 12 of thetemple arm 1 wherein Fig. 3(A) is a front view, Fig. 3(B) is a sectional view taken along the lines B-B of Fig. 3(A) and Fig. 3(C) is a rear view. - First, the
temple rod 11 is linearly formed and thetip end 11A of thetemple rod 11 is bent substantially perpendicularly. An ear pad is fixed later to the rear end of thetemple rod 11. - Meanwhile, the
shaft 12 is formed columnar as shown in Figs. 3(A) to 3(C), and a throughhole 12B provided perpendicularly relative to the axis of theshaft 12 by penetrating theshaft 12. - A
recess 12A is provided on the outer periphery of theshaft 12 in the axial direction thereof and therecess 12A has a depth in which thetip end 11A of the temple rod is completely engaged or thetip end 11A slightly protrudes from therecess 12A after engagement therein. - It is preferable that the width of the
recess 12A is narrower than the thickness of thetemple rod 11, which will be described later. - As a material of the
temple rod 11, all metals which have been now used in eyeglasses can be used, particularly, metals such as stainless, a Ti-alloy such as β-titanium, etc., titanium-nickel alloy. - Although a material having a given elasticity is employed as the material of the
shaft 12, it is preferable to employ, for example, nylon, polyacetale, polycarbonate, fiber resin, ABS, AS, acrylic plastic, polyester, polyethel, nylon elastomer, etc. because they have proper elasticity. - Figs. 4(A) to 4(C) are views showing a sequence to attach the
shaft 12 to thetemple rod 11. - The
temple rod 11 is inserted into a throughhole 12B provided in theshaft 12 from the other tip and opposite to thetip end 11A and thetip end 11A is finally pressed into therecess 12A of the shaft (see Figs. 4(A) → 4(B) → 4(C)). - In this case, since the
shaft 12 has a proper elasticity, thetip end 11A of the temple arm is elastically held by therecess 12A of the shaft, and hence thetemple rod 11 is prevented from readily drawing from therecess 12A once engaged therein. - Figs. 5(A) to 5(B) show the bracket 2, wherein Fig. 5(A) is a front view, Fig. 5(B) is a plan view, Fig. 5(C) is a bottom view and Fig. 5(D) is a perspective view.
- The bracket 2 includes a
shaft support 2A having ashaft support hole 21 to which thetemple arm 1 is attached. Theshaft support 2A comprises aguide groove 22 provided perpendicularly relative to the axis of theshaft support 2A and a notchedportion 23 adapted for outwardly opening theguide groove 22. - Accordingly, a T-shaped groove (a combination of the
guide groove 22 and the notched portion 23) is formed in theshaft support 2A. - The notched
portion 23 is provided in theshaft support 2A within an angle formed by the temple arm when swung since theshaft 12 is preferably positioned at the portion where theshaft 12 is easily attached to theshaft support 2A when theshaft 12 is attached to theshaft support 2A. - The
guide groove 22 has a sufficient width so that thetemple rod 11 can move along theguide groove 22 without generating play. - As the material of the bracket 2, alloys having a strength and working property such as nickel silver, monel, Ni based alloy, etc., are suitably employed.
- Figs. 6(A) to 6(C) are views showing an attaching relation between the bracket 2 and the
temple arm 1. - When the
shaft 12 of the temple arm is attached to the bracket 2, thetemple rod 11 is positioned under theshaft support 2A and it is passed through the notchedportion 23 of the bracket 2, then theshaft 12 is pressed into theshaft support hole 21 of the bracket 2 (see Figs. 6(A) → 6(B)). - Since the
shaft support hole 21 of theshaft support 2A of the bracket 2 has a diameter which is smaller than the diameter of theshaft 12 of the temple arm, theshaft 12 is attached to theshaft support 2A while the former is fastened by and engaged in the latter. - In a state where the
shaft 12 is mounted in theshaft support hole 21 of the bracket 2, thetemple rod 11 is guided along theguide groove 22 and smoothly swung as shown in Fig. 6(C). - Since the
shaft 12 is formed of plastics having proper resiliency, it becomes in a state where theshaft 12 is elastically mounted on theshaft support 2A, thereby providing proper resistance in a moderate sense in a swing movement of thetemple arm 1. - If the upper portion of the
shaft support hole 21 of theshaft support 2A is closed, theshaft 12 mounted in theshaft support hole 21 is not seen from the outside, so that theshaft support 2A looks better (not shown). - When the
temple arm 1 is attached to the bracket 2, theshaft 12 of the temple arm may be pressed oppositely to the direction shown in Fig. 6(A) (not shown). - When the
temple rod 11 is attached to theshaft 12, first thetemple rod 11 is inserted into and passed through the throughhole 12B of the shaft, then thebent tip end 11A is engaged in therecess 12A provided on the outer periphery of the shaft, as described previously. - Accordingly, the
tip end 11A of the temple rod may be bent not only in one direction (e.g., upward direction) but also upward and downward directions, and in the latter case the upper and lower tip ends are engaged in the recess provided on the outer periphery of the shaft, thereby more stabilizing the fixing force therebetween. - Figs. 7(A) and 7(B) are views showing a connecting state between the
tip end 11A which is bent in upward and downward directions and theshaft 12. - As shown in Figs. 7(A) and 7(B), the
temple rod 11 is inserted into theshaft 12, and thetip end 11A is engaged in therecess 12A so that thetemple rod 11 is attached to theshaft 12 in a state where thetemple rod 11 is slightly protruding outward from the outer periphery of the shaft by a distance L in Fig. 7(B). - Figs. 8(A) and 8(B) are views showing a connecting state between the
tip end 11A which is bent in upward and downward directions and theshaft 12 like Figs. 7(A) and 7(B), wherein when theshaft 12 is inserted into and fixed to thetemple rod 11, thetip end 11A is engaged in therecess 12A and thetip end 11A does not protrude outward. - Figs. 9(A) and 9(B) show an example of forked branched
temple rods - There are provided crossing
grooves 12C on the upper and lower portions of theshaft 12 which cross theshaft 12 in the radial direction of theshaft 12 and the forked branchedtemple rods crossing grooves 12C. That is, thetemple rod 11 is elastically pressed against and attached to theshaft 12 in the manner of clamping a so-called middle wall of theshaft 12 by a pair of forked branchedtemple rods recesses 12A provided on the outer periphery of theshaft 12. Theshaft support 2A corresponding to theshaft 12 is shown in Fig. 13(A) and 13(B). - It is preferable that the
temple arm 1 is stopped in a stable state in the positions where thetemple arm 1 is collapsed relative to the frame of the eyeglasses. - In a second embodiment as shown in Figs. 10(A) and 10(B), recesses 22A are formed in a
guide groove 22 of a bracket 2 wherein atemple rod 11 is engaged in one of therecesses 22A when it is positioned at either end of theguide groove 22. It is preferable that thetemple rod 11 is slightly moved in the axial direction (downward in the figure) in order to engage thetemple rod 11 in therecesses 22A (see Fig. 10(B)). - In a third embodiment as shown in Figs. 11(A) and 11(B), a
temple arm 1 can be stopped in a stable state in the positions where thetemple arm 1 is closed or opened relative to the frame of the eyeglasses like the second embodiment whereinlongitudinal grooves 21A are formed in the inner surface of ashaft support hole 21 of the bracket 2 in the axial direction (see Fig. 11(A)). - As the
temple arm 1, there is employed a temple arm having abent tip end 11A of the temple rod 11 a part of which is slightly protruding from the outer peripheral surface of ashaft 12 in a state where thebent tip end 11A of thetemple rod 11 is engaged in arecess 12A. - If the
shaft 12 is mounted in theshaft support hole 21 of the bracket 2, thebent tip end 11A of thetemple arm 1 is engaged in thelongitudinal grooves 21A and the stopping state of thetemple arm 1 is stabilized in a state where thetemple rod 11 is positioned at both ends of theguide groove 22, namely in the closed or opened state of the temple arm 1 (see Fig. 11(B)). - In a fourth embodiment as shown in Figs. 12(A) and 12(B), a cushion function is performed between a part of a
temple arm 1 and a bracket 2 in a state where thetemple arm 1 is opened. - That is, a flexible member D which performs a cushion function is interposed between the part of the
temple arm 1 and the bracket 2. In this case, a notchedportion 23 of ashaft support 2A of the bracket 2 is formed to be slightly wider than the diameter of the temple arm. - The flexible member D is provided at the root of a
temple rod 11. When ashaft 12 of the temple arm is mounted in ashaft support hole 21, the flexible member D is compressed and can pass through a notchedportion 23 together with the temple rod 11 (see Fig. 12(A)). - If the
temple rod 11 is opened and positioned in one end of aguide groove 22 in a state where theshaft 12 is mounted in theshaft support hole 21, the flexible member D performs a cushion function because the flexible member D is provided between thetemple arm 1 and the end of the guide groove 22 (see Fig. 12(B)). That is, in the open state of the temple arm, thetemple arm 1 can softly contact the face when wearing eyeglasses because the flexible member D performs a cushion function. - In a fifth embodiment as shown in Figs. 13(A) and 13(B), there is described a turning mechanism using a
temple arm 1 having the forked branchedtemple rods - A bracket 2 has two
guide grooves portion 23 communicates with theguide grooves - It is possible to simply attach a
shaft 12 of a temple arm to the bracket 2 by passing branchedtemple rods portion 23 of the bracket 2 in the same manner as the previous embodiments. - In a state where the
shaft 12 is mounted in theshaft support hole 21 of the bracket 2, the branchedtemple rods guide grooves temple arm 1 is highly stabilized and smoothly performed. - In the first to fifth embodiments, the tip end of the temple arm is bent but in a sixth embodiment, the
tip end 11B of the temple arm is enlarged at both sides to form a sectorial shape. - Figs. 14(A) to 14(C) and Figs. 15(A) to 15(C) show a sixth embodiment of the invention.
- Figs 14(A) to 14(C) show a sequence of attaching the shaft to the temple rod, where Fig. 14(A) is a perspective view before the attachment thereof, Fig. 14(B) is a perspective view at the time of insertion therebetween and Fig. 14(C) is a perspective view after the attachment thereof.
- Fig. 15(A) to 15(C) are views showing attaching relation between a bracket 2 and a
temple arm 1. Atemple rod 11 is linearly formed and thetip end 11B of thetemple rod 11 is enlarged at both sides to form a sectorial shape. - In this case, the
tip end 11B of thetemple rod 11 is designed to have a large diameter and thetip end 11B having the sectorial shape can be obtained by subjecting thetip end 11B to a smashing process by forging. - The
shaft 12 is formed columnar and anexpansion space 12D is formed in a throughhole 12B which penetrates perpendicularly relative to the axis of theshaft 12 to be opened outward. - To attach the
temple rod 11 to theshaft 12, thetemple rod 11 is inserted into the throughhole 12B of theshaft 12, then thesectorial tip end 11B of the temple rod is pressed into theexpansion space 12D of the shaft (see Figs. 14(A) → 14(B) → 14(C)). - In this case, if the thickness of the
tip end 11B of the temple rod is set to be slightly longer than the spatial thickness of theexpansion space 12D of theshaft 12, thesectorial tip end 11B is elastically held by theexpansion space 12D owing to the proper resiliency of theplastic shaft 12 so that thetemple rod 11 once engaged in theshaft 12 is prevented from readily drawing therefrom. - Since the
sectorial tip end 11B of the temple rod has a relatively large area, the connecting force between itself and theshaft 12 is sufficient and thetip end 11B and theshaft 12 are integrated with each other, resulting in no generation of a play therebetween. - The manner of attaching the
shaft 12 to the bracket 2 is the same as that described in the first embodiment. - Since a
shaft support hole 21 of ashaft support 2A of the bracket 2 has a diameter slightly smaller than the diameter of theshaft 12, theshaft 12 is attached to theshaft support 2A while the former is fastened by and engaged in the latter. - Accordingly, the swing movement of the
temple arm 1 relative to the bracket 2 is moderate (resistive), which is the same as set forth in the aforementioned embodiments. - The invention has been described with reference to the aforementioned embodiments, but it is not limited to these embodiments and it can be modified variously.
- For example, the external shape of the shaft support is not limited to a circular shape but may employ a square or rectangular shape.
- Further, although the shaft support is provided at the bracket side and the shaft is provided at the temple arm side, it is needless to say that they may be provided vice versa.
- Since joints are not used, screws do not loose to obtain proper resistive feeling when swinging the temple arms.
- Since the shaft and the temple arms can be surely attached by insertion and engagement therebetween without heat such as brazing or the like, the shaft can employ plastics as a material thereof.
- The proper resiliency of plastics renders the swinging resistance of the temple arms more appropriate.
- The temple arms and the brackets can be simply attached to each other in a snap.
- The features disclosed in the foregoing description, in the claims and/or in the accompanying drawings may, both separately and in any combination thereof, be material for realising the invention in diverse forms thereof.
